In a softball interview, Snowden told sympathetic reporter James Bamford the US still has no idea how much classified information he swiped — and then slammed the NSA for “negligent auditing” of its massive inventory.

The NSA told The Post that if Snowden has something to say, officials there would he happy to talk to him — in the United States.

“If Mr. Snowden wants to discuss his activities, that conversation should be held with the US Department of Justice,” said NSA spokeswoman Vanee Vines.

Snowden made off with tens of thousands of stored US intelligence documents in 2013, when he boarded a plane to Hong Kong and later made his way to Russia. He has been indicted for violations of the Espionage Act for what has been called the largest intelligence leak in history.
